### Restricted content

Restricted content on this site marked with the <ClosedAccessLink to="#content">lock icon</ClosedAccessLink> includes the following:

- The photo of me appearing on the [home page](/) was taken by [SPOT Fotókör](https://spot.sch.bme.hu/) in 2019 for the [Critical Systems Research Group](https://ftsrg.mit.bme.hu/).

- The drone shot of BME building I appearing in the [Contact](/#contact) section was taken by [Ákos Hajdu](https://hajduakos.github.io/) in 2020 for the [Critical Systems Research Group](https://ftsrg.mit.bme.hu/).

- Unfortunately, some of my [publications](/#publications) appeared in closed access journals and proceedings. Even though neither me nor by colleagues received any compensation, the copyright of this content was assigned to the publisher, such as ACM or IEEE.

  Whenever allowed by the current copyright holder, I posted the _final draft_ of the paper to this site.
  For papers published by ACM, I also created a link with the [Author-Izer](https://www.acm.org/publications/authors/acm-author-izer-service) to the _version of record_ of the paper. Such links only work if your browser sends my site as the [HTTP referer](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Referer) to ACM.

- My [PhD thesis](pathname:///phd-thesis.pdf) and its [extended abstract](pathname:///phd-thesis-booklet.pdf) also incorporates content whose copyright was assigned to a publisher. I'm also required to add the following disclaimer:

  > &ldquo;In reference to IEEE copyrighted material which is used with permission in this thesis, the IEEE does not endorse any of Budapest University of Technology and Economics&rsquo; products or services. Internal or personal use of this material is permitted.

## Code

Code for this site is available at https://git.marussy.com/blog/ under the <MITLicenseLink /> license.
Files with [restricted content](#restricted-content) were replaced by placeholders or omitted entirely.

I follow the [REUSE Specification – Version 3.0](https://reuse.software/spec/) to declare copyright and licensing for each individual file.
In particular, files which contain _both code and content_ (e.g., content inside complex JSX components) have the [SPDX License identifier](https://spdx.org/ids) `MIT AND CC-BY-4.0` to signify that they are both <MITLicenseLink /> and <CCBYLicenseLink />.
If you use only code or only content from such files, you only need to abide by the _corresponding license_ (<MITLicenseLink /> or <CCBYLicenseLink />, respectively).
